Current Implementation

As described in https://github.com/corona-warn-app/cwa-documentation/issues/672#issuecomment-899384824:

Adding a local 7-day incidence without internet connection now no longer just does nothing while offline but already adds the card to the Home Screen. However, the card is empty (because CWA couldn't download the incidence from the internet - makes sense) Here's a screenshot:

After connecting to the internet, closing and reopening the app, the value is shown:

Suggested Enhancement

Align the behavior under iOS to the behavior under Android, where a warning message is shown: "Your Internet connection was lost. It was not possible to add a 7-day incidence figure. Please check the connection and try again."

Expected Benefits

I think that the Android implementation is more user friendly, since the user is informed what's the problem. Currently, the user just sees a empty tile and wonders what went wrong...
